Couple of questions about them:
A) I've noted that in Nick Kyme's 'Tome of Fire' Salamanders novel series, there are repeated mentions of the Badab War markings being hazard markings on the left kneepad - despite the novel being set after the Badab War. However, I can find no mention of this marking in
IA10 (Parts One and Two). So, in the absence of info from
IA10 (The definitive source for the Badab War) can I assume that Nick Kyme's markings are canonically correct?
B) Are campaign markings only temporary for the duration of the campaign and then removed or are they more of a personal thing, whereby Space Marines individually choose to keep or discard the markings by way honouring a victorious or possibly a particularly bloody campaign?
Any help would be most appreciated
